Lines or ripples in nails can indicate normal aging, minor trauma, or sometimes an underlying health issue. The exact type of line matters.
🧠Types of nail lines & ripples
1. Vertical ridges (from cuticle to tip)
- Most common and often normal, especially with age
- Can be caused by:
- Dry nails
- Mild nutrient deficiencies (iron, B vitamins)
- Usually harmless if nails are otherwise healthy
2. Horizontal lines (across the nail)
- Known as Beau’s lines
- Deep grooves appear when nail growth temporarily stops
- Causes can include:
- Severe illness or infection
- Surgery
- Physical trauma to the nail
- They usually grow out over time
3. Pitting or small dents
- Looks like tiny depressions or ripples
- Often linked to skin conditions:
- Psoriasis
- Eczema
4. Discoloration or white lines
- Minor trauma is common
- Could reflect mineral imbalances (rarely serious)
🚨 When to see a doctor
- Sudden or worsening lines
- Brittle, discolored, or separating nails
- Accompanied by fatigue, hair loss, or rashes
đź‘Ť Nail care tips
